Invalid font name

[Joon Ro]

Hi,

I am using GNU Emacs 24.3.1 (x86_64-suse-linux-gnu, GTK+ Version 3.6.4). I
have custom font Inconsolata-g in my ~/.fonts folder, and I have set it as
the Monospace font in ~/.config/fontconfig/fonts.conf.

It works well except Emacs is giving me error: Invalid font name,
-unknown-Inconsolata-g-normal-normal-normal-*-15-*-*-*-m-0-iso10646-1 at
launch.

If I change monospace font (to a DejaVu Sans Mono, for example), then Emacs
launch without problem, but when I do M-x set-default-font, and select
-unknown-Inconsolata-g-normal-normal-normal-*-*-*-*-*-m-0-iso10646-1, I
also get Invalid font name:
"-unknown-Inconsolata-g-normal-normal-normal-*-*-*-*-*-m-0-iso10646-1",
even though I inputted it through auto-completion.

Best,

Joon
